Abstract: 403,656. Progression wheel or riser traverse mechanism for yarn winding machines. LEEDHAM, L. H., COLEY, J., and WILDT & CO., Ltd., Adelaide Works, Leicester. June 23, 1932, No. 17772. [Class 120 (ii).] In traverse mechanism for yarn-winding machines of the kind wherein a progression or riser wheel operatively connected with the yarn guide is mounted on a screwed spindle, the yarn-guiding means is so arranged that the resultant pull of the yarn is in a direction spaced from the axis of the riser wheel a radial distance substantially not greater and preferably less than the radius of the wheel. Pigtails, or, as shown, porcelain guides 15, 18 with end guiding-horns, are carried by a riser bracket 10, 11 formed as a steel pressing, and the yarn is guided by the lower horn of each. The guide 15 is substantially parallel to the axis of the riser wheel 19 and the guiding- portion of both guides is below the wheel. The guide 18 is inclined or otherwise spaced so that the upper horn is radially beyond the periphery of the wheel to permit of threading. The riser wheel engages with the threads of the screwed spindle 21 by means of a sliding plate 22 as described in Specification 324,292, [Class 120 (ii), Spinning, twisting, &c.], and a lightly biassed back-stop pawl 119 is provided. The arm 10 of the riser bracket engages a guide rod 24 which is braced to the screwed spindle 21 by a spacing-piece 26, the guide rod and screwed spindle being carried by a bracket 25 secured to the riser bar 27. The riser wheel is journalled in a bush 12, Fig. 5, of the riser bracket by a bush 120.

Abstract: 477,407. Converting ; control systems for consumption apparatus. GENERAL ELECTRIC CO., Ltd., and DUNHAM, C. R. June 26, 1936, No. 17820. [Classes 38 (ii) and 38 (iv)] Switching control; thermionic and like control. -The discharge in a gas-filled triode 5 on D.C. supply is extinguished by the application of a peaked voltage impulse in the anode circuit by means of a transformer having three windings 7, 8, 9, of which the winding 7 is in the anode circuit, the winding 8 is supplied with A.C. and the winding 9 is supplied with D.C. The arrangement of the windings and their currents is such that each is capable of saturating the core and the windings 7 and 9 are opposed so that when anode current is flowing, the two coils neutralize each other and permit the current in the winding 8 to inject a peaked impulse into the anode circuit to extinguish the arc. When no anode current is flowing, the winding 9 saturates the transformer and suppresses the peaked impulse in the opposite half cycle of the A.C. in the winding 8. As applied to a parallel type inverter, Fig. 2, one winding of the transformer is supplied with A.C. of the desired frequency and the other two windings 7, 9<1> ; 9, 71 are in the anode circuits of the valves 5, 5<1>. The arrangement is such that, at the moment of commutation when both coils 9, 7<1> and 7, 91 carry current, their effects neutralize each other and leave the coil 8 free to inject a peaked impulse of appropriate sign into the anode circuits of the valves so as to reduce the anode voltage of the outgoing valve and increase that of the incoming valve. British Specifications 382,612, 412,911, and 418,144, and U.S.A. Specification 1,945,401 are referred to.

Title: Improvements in or relating to the polymerisation and interpolymerisation of ethylene
IPC: C07C1/24
Filed: 1943-11-03
Abstract: In the manufacture of solid and semi-solid polymers and interpolymers of ethylene at elevated temperatures and pressures, ethylene free from, i.e. containing less than 0.1 per cent by volume of, carbon monoxide is used.  The presence of carbon monoxide may be avoided by control during the manufacture of the ethylene by catalytic dehydration of ethanol, by maintaining a high flow rate, maintaining the temperature between 300 DEG  and 350 DEG  C., by using ethanol free from oxygen and aldehydes, and by avoiding the presence of oxygen and copper and mild steel reaction vessels.  Alternatively, commercial ethylene may be freed from carbon monoxide by fractional distillation, e.g. in a packed column in which the pressure is 30 atmospheres and the temperature 0 DEG  C. at the bottom and 85 DEG C. at the top of the column.  The carbon monoxide may also be removed as carbonyl using catalytically active nickel.  Specifications 471,590, 497,643 and 8070/40, as open to inspection under Sect. 91, are referred to.

Filed: 1924-08-01
Abstract: Viscose silk in the form of yarn or fabric is desulphurised and lustred during the dyeing, mordanting or clearing (removal of surplus dye) process, so that its greater strength when in the sulphur state is retained as long as possible.  Examples show desulphurisation by means of sodium sulphite in baths containing direct colours, or basic colours and tannic acid, and in the tannic acid mordant bath for basic colours, and by means of sodium sulphide in vat and sulphur dye baths.  Another example shows the addition of sodium sulphite to the clearing bath after forming an azo dye on the fibre.  Ammonium or potassium sulphite may in all cases be substituted for sodium sulphite.ALSO:Viscose silk in the form of yarn or fabric is desulphurized and lustred during the dyeing, mordanting or clearing (removal of surplus dye) process, so that its greater strength when in the sulphur state is retained as long as possible.  In examples the yarn in the sulphur state is dyed in baths containing (a) for direct colours Direct sky blue FF and sodium sulphite, (b) for vat colours Caledon brilliant purple RR, caustic soda, sodium hydrosulphite, and sodium sulphide, (c) for sulphur colours Cross Dye green and sodium sulphide, and (d) for basic colours Brilliant green crystals tannic acid and sodium sulphite, the yarn being after-treated with antimony salt.  In an alternative method for basic colours the yarn is first treated in a bath of tannic acid and sulphite, extracted and placed in a bath of antimony salt, washed and finally dyed in a bath containing Brilliant green crystals.  For a developed colour the yarn is entered into a bath containing primuline and sodium sulphite, rinsed and extracted and then diazotized and developed with b -naphthol, or the yarn is treated with naphthol AS and then with diazotized dianisidine and desulphurized in the clearing bath by adding sodium sulphite as well as soap.  Ammonium or potassium sulphite may in all cases be used instead of sodium sulphite.

Abstract: 555,932. View.finders. KODAK, Ltd. Dec. 28, 1942, No. 18426. Convention date, Jan. 23. [Classes 97 (i) and 98 (i)] A variable-field view-finder has means for defining substantially concentric rectangular fields, corresponding to different angles of view, comprising one or more plane polarizing filters defining the area between successive rectangles and a selector plane polarizing filter mounted so that it may be rotated to render the first filter, or a selected one of them, effectively clear or opaque. Fig. 1 shows an inverted Galilean type finder in which a frame 10 of polarizing material is mounted in front of the negative lens 14 and a plane polarizing filter 11 is rotatably mounted in front of the eye lens 15, so that it may be adjusted to render the portion of the field covered by the frame 10 clear or opaque. A directvision lensless finder, a real-image finder, and a reflex brilliant type finder having the invention applied to them are also illustrated. Fig. 7 shows an arrangement giving four sizes of field, in which three frames of polarizing material are provided, having their polarization axes oriented as shown by the arrows at 80. By rotating the selector filter so that its polarizing axis lies in one of the directions shown by the arrows at 81-84, the corresponding appearances shown at 81<SP>1</SP>-85<SP>1</SP> are produced. In the last case, the selector filter may be removed altogether, as indicated at 85. The slight darkening of the areas for which the selector filter is between the clear and opaque positions, for example the rectangles adjacent the opaque rectangle shown at 82<SP>1</SP>, is negligible. The centre area of the field may be provided with a neutral density equal to that of the polarizing filters combined with their polarizing axes at 45 degrees to one another.

Title: Process for the manufacture of complex metal compounds
IPC: C07C51/41
Filed: 1931-06-26
Abstract: Complex metal compounds of aliphatic polyhydroxy-monocarboxylic acids, soluble in water with a neutral reaction, are prepared by treating the acid with an oxide, hydroxide or salt of a metal whose atomic number is greater than 26 (excluding the alkali and alkaline earth metals), effecting neutrality by the addition of a basic compound of calcium or strontium, and isolating the products from the solution.  Alternatively, the calcium or strontium salt of the acid is employed as starting material.  The acids are those derived from sugars, e.g. arabonic acid, 2-methylpentane-tetrolic acid, gluconic acid, galactonic acid, lactobionic acid, glucoheptonic acid, mannoheptonic acid, or their equivalent lactones.  As basic calcium or strontium compounds may be employed the oxides, hydroxides and carbonates, or a mixture of a calcium or strontium salt with an alkali.  The metals may be combined to form the complex compounds in varying proportions.  According to the examples, (1) gluconic acid, calcium hydroxide and arsenious acid are boiled with water and the calcium-arsenic gluconate precipitated by pouring the solution into methyl alcohol; (2) calcium gluconate is added to a solution of lanthanum carbonate in hydrochloric acid, then heated with calcium carbonate and the calcium-lanthanum gluconate isolated as in (1); (3) calcium-antimony gluconate is prepared by heating a suspension of calcium gluconate with antimony trichloride, adding milk of lime, filtering and pouring the filtrate into methyl alcohol; (4) gluconic acid lactone is treated with lead acetate or stannous chloride and milk of lime added; the resulting lead and tin complex compounds are isolated by pouring into methyl alcohol. Reference is made to the production of calcium-antimony and calcium-lead glucoheptonates, and of complex compounds of copper and tetravalent tin.  Specification 352,928 is referred to.
